TCR VALUES

[Saintskinny51792]

hey all, im planning on buying the istick tc100w in the next couple weeks, if all goes well. Ive been watching reviews and seeing that you can change the tcr values, after a little research ive gotten this far;
If youve got, lets say an istick. its SS mode is for whatever ss alloy they used in their ss coil heads. if they use ss 316 in there coil heads and your doing a build with ss 304, the TC will be off (not sure by how much but some people are finicky with their vaping.) So, from what I read, in that scenario you should look up the TCR value of the alloy that your using and plug in the numbers in TCR mode instead of reg SS-TC mode.

My question is, can you put in the tcr for something like NiChrome and use it in TC? Im familiar with how TC works but my TC40W doesnt have all those variables so im clueless here

Well the basic premise for using TC vapaing is that the wire changes its resistance appreciably as it heats up. So firstly, nichrome does not do that and, like kanthal, cannot be used in TCR-based temperature regulated vaping!

Selecting the right TCR is not being finicky! it is absilutely crucial to getting it to work properly. This is particulalrly the case for SS where all of the alloys (304, 316, 216L, 317 etc etc) all have a very low TCR compared with, say, Ni200, Ti, NiFe alloys. Small errors in the estimated resiatnce and errors in the TCR will make for a poor or bad experience.

Here's a thread that has every TCR you would probably ever want: The Ultimate TCR List.

ive seen a couple mods that do TC with nichrome, from what ive seen it does change resistance when heated, maybe just not as much of an ohm change (would that be a lower TCR?) if nichrome 80 is 80% nickel (not sure on that fact but ive heard it a few times) it seems like it would work but idk ive only used Kanthal and Ni200.

Finicky was a bad word to use, I kinda meant are more into the tinkering aspect and would like things dialed in further. some people will just say something like 'Well, ss is ss so its close enough for me'

 

[Wingsfan0310]

The smaller the TCR is, the less resistance change there will be. With less resistance change, comes less accuracy. When you are talking about such minute changes the slightest thing will throw everything off.
EX: the connection of the coil to the atomizer, the atomizer to the mod, internal resistance of the mod, etc.

I find SS 316L to be finicky because of it's low TCR. I've recently switched over to SS 430 because it's TCR is ~50% higher. Comparatively speaking 316L is a walk in the park compared to Nichrome or Kanthal which I consider not suitable for TC. Just because a mod claims it can do it, that doesn't mean it actually can. Just my .

Yes.
You just need to know the tcr value for nichrome.

okay that's what I thought, thanks! It seems like having that option could be nice in the future, who knows what type of non/resistance wire will be coming around... Vaping is one of those areas that are always changing, usually for the better!

 

[TheotherSteveS]

ok, I'll say this once more and you can believe me or not. The TCR value of most available nichrome alloys is around 5-10x lower than SS 316 (Kanthal A1 is 50 or more x lower than that so if you want to try it, knock yourself out You better make sure your build is spectaculalry good, and resistance pretty high otherwise I guarantee it will be a bag of hurt...

ps. the mods that use nichrome ( the iJoy Asolo and derivatives) are the ones that try to do a version of TC that they call dry-hit protection. These use a different method and it is significant that they generally recommend using nichrome as the higher (but still small tcr) gives them a better chance of getting it right... The new Joyetech system uses a heat sensor in the tank to try to measure the temp directly. In this case it doesnt matter what wire you use.

 

[Saintskinny51792]

nichrome was more of an example than anything. I just meant any wire the mod didnt have settings for, ya know? I was more thinking of using SS alloys myself. but ill prolly try a couple other things just for the halibut! Ill ask Gill, he's the club flounder lol I crack me up when im so punny

 

[Wingsfan0310]

On the third post I gave you the link to the TCR thread. It has TCR's listed for any wire you could think of. Did you check it out?

yes the ss alloys have better tcr values than nichrome.
you can compare tcr values on steam-engine.org

At first glance looking at that thread (whicch is 4 pages long)

it looks like the tcr for nichrome is:

0.00040

oh, wait, maybe it's

0.0040

oh wait.

maybe it's
40?

Are you being serious or just trolling? You do realize Joyetech boards manual TCR's are input with a multiplier of 10 right? It's listed both ways, the normal TCR and the one you would use for a Joyetech mod (it's clearly marked as such)

Whats is your point???
For the hard of hearing here we go.
TCR @20C
Nichrome 80 - 0.000112
SS316L - 0.000880
Ti Gr1 - 0.00366
Ni200 - 0.00609

So Nichrome has a TCR around >50x lower than Ni200

hard of seeing; all those zero's look like gooblygook through my pharmacy glasses

Now, "50x lower than Ni200": THAT I Understand.

Thanks.

when things are some numbers shown to 6 decimals and others only 5, it gives the impression there might be a typo.

NiCr is possilbe the Kanger kbox mods do it

As I've already said once in this thread, just because a mod claims it does TC on Nichrome doesn't make it so. Here's a video showing it failing miserably on a cotton burn test with Nichrome. The test starts at about 3:45, don't forget to bring the marshmallows

just get a roll of ti wire. good tcr/resistance qualities. works great for tc.

i have one and ill tell you it wont burn the cotton with NiCr wire in TC, if anything it seems a little underpowered, i wouldnt trust anything that hack mike says, hes a douche nozzle of the first degree

That was just one of the reviews that said it didn't work. Have you tried a cotton burn test? Most people think reviewers say everything is good to keep the freebies coming, not that they make up negatives. Is this guy wrong too?
